ibm: bios for auto poweron control

On IBM systems, the host firmware can control the auto power on logic.
Map a new pvm_auto_poweron_restart BIOS value to the corresponding
D-Bus property.

Tested:
- Enabled test - verify enabling bios value sets AlwaysOn to d-bus prop
root@p10bmc:~# pldmtool bios SetBIOSAttributeCurrentValue -a pvm_auto_poweron_restart -d "Enabled"
{
    "Response": "SUCCESS"
}
root@p10bmc:~# busctl get-property xyz.openbmc_project.Settings /xyz/openbmc_project/control/host0/power_restore_policy xyz.openbmc_project.Conrol.Power.RestorePolicy PowerRestorePolicy
s "xyz.openbmc_project.Control.Power.RestorePolicy.Policy.AlwaysOn"

- Disabled test - verify disabling bios value sets None to d-bus prop
root@p10bmc:~# pldmtool bios SetBIOSAttributeCurrentValue -a pvm_auto_poweron_restart -d "Disabled"
{
    "Response": "SUCCESS"
}
root@p10bmc:~# busctl get-property xyz.openbmc_project.Settings /xyz/openbmc_project/control/host0/power_restore_policy xyz.openbmc_project.Conrol.Power.RestorePolicy PowerRestorePolicy
s "xyz.openbmc_project.Control.Power.RestorePolicy.Policy.None"

- Verify setting d-bus prop is reflected in bios
root@p10bmc:~# pldmtool bios  GetBIOSAttributeCurrentValueByHandle -a pvm_auto_poweron_restart
{
    "CurrentValue": "Enabled"
}
root@p10bmc:~# busctl set-property xyz.openbmc_project.Settings /xyz/openbmc_project/control/host0/power_restore_policy xyz.openbmc_project.Conrol.Power.RestorePolicy PowerRestorePolicy s "xyz.openbmc_project.Control.Power.RestorePolicy.Policy.None"
root@p10bmc:~# pldmtool bios  GetBIOSAttributeCurrentValueByHandle -a pvm_auto_poweron_restart
{
    "CurrentValue": "Disabled"
}
